Application filed March 1 1924. Serial No. 699,164.

To all/10710921. it may] com em:

it known that l, C'llARLES A. lmcxcsr. at citizen of the United States, and v. res1- (lent or (.rotcn Falls, in the count; of West- 6 cheater and State or New 3 orh have m in the book covering inschine by which the covers ere applied to. the backs oi the truvch in; books so that the operation of the machine through the successive cycles will be both ziutonietic and continuous throughout,

thereby dispensing with. necessity oi constant attention by the operator.

The main ob ects 01' my present lnventmn are, among other things, to provide an unproved and. simplified book covering innrhino of this character whereby the path of the books through the machine may be nuaintsined substantially in a horizontal slrui ht line; also to provide means wli rob; the coecting hook clumps used to hold the books firmly in position on the carrier and mounted in pairs thereon may have on opening and closing movement in mutual parallelism and. may collectively more in vertical ulinenient with the line or p51 ill of the successive books advancing through the machine. strut-lion and eoordination between the successive devices employed for applying the covers lo the books precludes any disarrangcnient in the several books in their straight line progress through the machine,

and zilso enables the covers to be applied to the lowern'iost, backs with greater accuracy and register while the books are held and forwurded by the successive pairs of clumps in upright position from one operating derice to enother. By my iniprow'sincnt the boolcs may be speedily handled and the 'iivcly as shown in Figs. 23

Such feature oi? improved con-- covers applied with greet ellectiveness and precision. Further ObjfiCtS and advantages will hereinel'ter be set forth and be particularly pointed out III the claims; my nnprcvernents,

may be embodied either in the preferred forin of book covering machine herein shown or in various modified. forms to fit the particular conditions of usage in differ-- cnt types of machines of this general character.

Similar numerals refer to similar throughout the several figures.

Referring to the drawings, and more perticulerly Fig. l, the standards ll) support the hvo-spacedopart cross-shefts 11 and 12 on which are allixed separate pairs of spncedopart sprockets 13 and 1+l respecund 4. Each of these two sprockets 1.3 and 14 is vertically disposed end suflieiently spaced from the other to permit oi the opening and closing oi. the book-clamps hereinafter to be described. The shalt 12 rotated by bevel gear 15 which meshes with the bevel gear 16 on the upright shaft 17 on the lower end of which is securedthe bevel gear 18 ennnging the bevel gear 19 driven by the elem tric motor =20, or other suitable source of power, all as shown in Fig. 4.

The successive book clumps are hinged together to form an endless loop book conveyor passing around the pairs of sprockets 15a rts 13 and 14 as shown by the arrow in Fig. 1.

Each book clamp comprises two vertical disposed members 21 and 22 adapted to engage the sides of the books carried, the member 21 being journalled at each end to the cross-bars 23 as shown in Fig. 5, while the movable member 22 is slidably mounted at one end on the cross-bar 23 while the other end" is slidably mounted on the shaft 24. One endof the shaft 24 is securedin the member 21, while the opposite end is secured SllOWl'llTl Figs. 5 and 9. The link members 25 arejournalled to the cross-bars 23 to form one side of the endless book-conveyor, and the springs 26 and 27 coi ed about the cross-bars 23 and cross-shafts 24 normally exert a closing pressure on the book-closing movable members 22 as shown in Fig. 5: Pivoted to each end of the cross-bars 23 are the horizontal guide rollers 28 and 29 respectively adapted to fit inthe slots 30 and 31 formed in the sprockets l3 and 14 by which the successive pairs of booleelamps forming the book-conveyor are driven by such sprockets when revolved in a counter clockwise direction as shown in Fig. 1.

Each movable member 22 carries the camroller 32 which by engaging suitably disposed cams 33 and 34 opens the successive.

book clamps against the tension of the springs 26 and 27, as such book clamps progress through the machine.

The books are fed to my machine in upright position with their backs lowermost by any suitable mechanism. In the embodi- -ment shown in Fig. 1, the conveyor belt 35 passing around the pulley 3G journalled on the standard 10 advances the successive books 37 longitudinally extended along the side guides 38 and 39 adjacent the periphery of the sprocket l2 ready to be seized by the book clamps as shown in Figs. 1 and 3.

Arranged beneath the book conveyor is the glue pot 40 in which is rotatably secured the glue roller 41 which feeds the glue to beapplied to the backs of the successive books the lingers 4-5 on the upper run of the car-;

rier 44 and then around the drum 43 where they are applied gradually to the backs of the books, the drum pressing the cover progressively throughout its length. In the forward travel of: the lJOOk-(flillllPS on the conveyor the books 37 then pass to the cover in the link-member 25 as the 'aws of the bnliaker move inwardly to brea the cover inithe usual manner.

Tl e books the pass to the endlessdelivery conveyor 4 mounted on the pulleys -49 and 50 journalled in the standards 10 by which conveyor the mparate books travel along the delivery chute 51 to fold up the cover flaps around the book as shown in Figs. 6, 7 and 8, the sides 51 and 52 being inclined for this purpose, along the delivery conveyor 48 to transfer the covered books to any convenient form of stacker 53 located at the forward end of the standards 10 as shown in Fig. 1.

The cam 33 is affixed to the bracket 54 secured to the standard 10 (Fig. 3) so as to open the normally closed book clamps as shown when the latter begin their lower run. As shown in Fig. 1, the cam 33 starts at a point before the book clamps reach the side guides 38 and 39, and such clamps close on the book at the end of the forwardrun of the belt 35. In like manner the cam 34 is affixed to the bracket 55 secured to the standard 10 (Fig; 4) so as torelease the books as they pass into the delivery =chute 51 (Fig. 6). The cam 34 starts to open the book clamp gradually and holds them in open position until the book with its outspread cover 42 has reached its Fig.7 position on the conveyor 48.

It will seem from the foregoing that the forward travel of the books 37 when fed from the belt 35 to the book clamps on the conveyor and then through the successive operating devices for applying the covers to the books to the chute 51 is in a horizontal straight line with the book clamps opening and closing in mutual parallelism with the sides of the 'books. Furthermore such clamps have a revolving movement in the endless conveyor in vertical alinement with the path of the successive books through the machine. By such construction and operation the clamps have acombined transverse movement in opening and closing which produces an exceptionally firm hold on the book, and such clamps also move in vertical or upright position, shown more particularlyin Fig. 3, as the are brought into ac curate register with t e hooky-37 advanced by the conveyor belt 35; thereafter they are delivered with their covers 42 in the chute 51 in perfect alinement as shown in Fig.1)

with the books travelling in a horizontal straight path throughout the entire machine.

My improved book covering machine is simple in construction and pronounced advantages are attained by having the various devices for handling and opera-tin on the backs of the books held in upright position lgseosel arranged sis-shown in this preferred embodimerit of my invcntionwvith the books being vention rind Without sacrificing its chief."
